Dual USB
This module is not BUCK.
Make use of imported integrated switch ultra-thin regulator module manufacturing process and synchronous rectification technology so as the conversion rate is more than 96%, what's more, calorific value is extremely low.
This module is poted by epoxy so it's waterproof, shockproof, moistureproof, anti-dust and flame retardant.
The module boasts of automatic protection function when over voltage, over current, over temperature and short circuit braking and restore normal work after the conditions.

Single USB
Use imported and integrated switching regulator modules manufacturing,quality is stable and reliable.
Synchronous rectification,the conversion rate is 96% or more, very low heat.
Over current, over temperature, short circuit, reverse polarity, it can be auto protection,and can work in normal condition when restored.
Operating Temperature: Industrial (-40C to +85C) (ambient temperature exceeds 40 degrees, lower power use, or to enhance heat dissipation)
Epoxy potting, seismic, water, moisture, dust, long term stable and reliable quality.
Super-thin, small size, high efficiency, easy installation and use.
Work with most of cell phone,iphone 4 4s,IPAD,IPAD2,samsung Galaxy.
